The 2011 lineup of Ford's Super Duty F-Series trucks may not look all that different from the models on the road today, but a lot has changed under the hood. In fact, in a vehicle segment dominated by talk of horsepower, torque, and towing capacity, the new F-Series Super Duty trucks may just change the game, and make such terms as "inclinometer," "Single-Sequential Turbocharger" (SST), and "compacted graphite iron" (CGI) the new language of heavy duty pickups.
